PASTE-DRIER.

Application filed August 16, 1915.

To all whom 2'!- may; concern Be it known that 1, AUGUST TEGOLL, a citizen of the Kingdom of Italy, residing at Santa Rosa, in the county of Sonoma and State of California, have invented certain new and useful Improvements in Paste- Driers, of which the following is a specification.

This invention rel-ates to improvements in what may be generally termed driers, especially designed'for drying long paste, commercially known as macaroni, and the like.

The invention has for its object to provide for effecting the drying operation with facility, expedition and economy.

A further object is tosecure product of superior quality.

A still further object is to carry out the aforesaid ends in a simple and eliective manner.

The invention consists therefore of an airblast generating means in'connection with an air-heating chamber or chambers arranged for delivering or subjecting the article treated to regulated air-blasts, substantially as hereinafter more fully disclosed and defined by the appended claims.

In the accompanying drawings wherein it will be understood that various changes and modifications may be made as to the detailed construction and arrangement of parts without departing from the scope of the claims and in which drawings Figure l is a longitudinal section of my invention with certain parts broken faway. Fig. 2 is a horizontal section thereof with parts broken away. Figs. 3 and 4 represent sectional elevations of the same with parts broken away, respectively.

In carrying out my invention, 1 erect a general casing or housing 1, which may be of indefinite rectangular dimensions issug estcd by the broken away outlines, the same naving built in one side thereof an air exhaust funnel or chute 2, which is in communication with a. suction or exhaust gen- Thc chute 2 extends downwardly through the floor near its outlet. as at 3.

The suction generator or exhaust chute 2 is provided at its upper end with the horizontal shorter and longer diverging branches or pipes 4 and 4 which extend into the 1 separate heating con'ipartinents 3 and 4, re-

spectively,said heating compartments communicating with the drying chamber 5 through the transverse longitudinally spaced ports or openings 6 and 6 in the horizontal wall or partition A separating the heating compartments and the drying chamber, said ports or openings being equipped with the hinged closures or valves 7 and 7. The drying chamber 5 which is situated below the heating compartmentsor at theloottom of the casing and extends the entire length of the latter, is arranged to receive the cars or trucks 8 carrying, in upper and lower tiers,

the partitions or side walls a and'bjof the heating compartments: and connected. to the source of steam supply andexhaust chambers thereof (not shown) as well understood. Also arranged in the heating chambers 3 and 4, preferably as shown, in separate central transverse openings d in the partitions or side walls a and cthereof, are air-blast gen erating fans 12-, the bladesof which are secured to a. common shaft 13 journaled in suitably lubricated "bearings 14 mounted. upon the transverse bars or members as shown. Said shaft 13 .is equipped at its outer end with fast and loose pulleys 15 and 16, respectively, and in practice, it is driven by a belt from a motor (not shown) for driving or rotating the shaft andfan s in either direction as desired to change the direction of the blast from the fans, and accordingly change or reverse the direction in which the heated air travels in making a circuit through the drying chamber and heating chamber. The upper portion of the casing l is oiiset or extended at its rear end beyond the heating chambers?) and 4, as clearly shown more particularly .in Figs. 1 and '2, for providing an air circulating space 17 iii the top of the casing above the drying chamber and in rear of the heating compartments 3 and 4. An air circulating space 17 is also provided in the top of the casing above the drying chamber'5 and in front of the heating compartments, as shown.

indicated by the arrows,

, or saturated air Suitably positioned with its lower end at the bottom of the drying chamber directly below the offset or extension at the rear end of the casing above referred to, is an outwardly and upwardly inclined sliding door 18 provided at its upper end with hangers 19 equipped with the grooved traction wheels 20 traveling upon a track 21 overhanging the door for access to the interior of the casing and the drying chamber 5, at the rear.

In operation, the hung upon the sticks sticks placed in position in the trucks 8, the latter when filled, being then rolled into the casing in the drying chamber 5, as shown, after which'operation the casing and the drying chamber is completely closed and the valves or closures 7 and 7 all thrown :operl, 'The fans or generators 12 are nqw put in motion, setting up a circulation or blast of ,air through the drying chamber as any moist laden passing out at the outlet 25, controlled, Q the valve 26. The fans 12 may'be rotate'hdin either direction to cause the heated air to make a circuit through the heating chambers and drying compartment, that is, to change or reverse the direction in which the air travels or circulates through said chambers and compartments. To regulate the temperature of the air in the casing and prevent itfrom being heated to too great an extent, the valve 24 in the upper end of the exhaust chute 2 may be opened temporarily to draw off some of the heated air through the branches or pipes 4 and 4: of the exhaust chute and through the latter and the exhaust chamber 2 to the outside or exterior, and the valve 23 at the upper end of the exhaust chute 2 then opened'to allow a fresh quantity or supply of unheated air to enter the casing, as is apparent.

Among advantages of my invention, duces the time of drying about from a Week to a day and a half or the time maybe reduced even eighteen hours if this be desired. It uses but a fraction of the space required by the employment of other methods, it prevents souring or molding, preserves the original light color of the goods and avoids curling, cracking or breaking, also insures uniform drying; its capacity is about a ton of dried paste.
